摘要： An evaporation heat exchanger having at least one active circulating circuit for a coolant liquid to be cooled, is constructed for removing heat in a spacecraft under a gravity-free operating condition and under different acceleration conditions. For this purpose, a housing encloses an evaporating space provided with at least one inlet valve for controlling the admission of a medium to be evaporated. The produced vapor or steam is discharged through a respective port. A plurality of cooling tubes interconnected in a meandering shape form a number of tube panels in which the individual tubes are arranged in a zig-zagging pattern to form respective flow passages for the medium to be evaporated. The individual tubes extend in parallel to each other and perpendicularly to the flow direction of the medium to be evaporated, while the meandering configuration is forming the zig-zag pattern. This arrangement of the cooling tubes assures a high efficiency in the heat transfer and also in the complete conversion of the liquid to be evaporated into vapor or steam. Due to the zig-zag pattern, the medium to be evaporated, or droplets thereof, are repeatedly intercepted and deposited by the exchanger surfaces of the tubes so that the exchanger functions as a drip-catcher evaporator.
